The transformer I had (which ultimatly went back to Ronnie/W5SUM when he
got my 450TL's) was labled a "Sola Constant Voltage Transformer".

90 ~ 150v input, 7.5v ouput @ 42amps.

I remember hooking the thing up one time, to check some tubes (450's)
and with just the primary connected, the durn thing was 'noisey'.  Made
noise, just sitting there, with no load.  Noise didn't change with a
load, either, but that transformer sure did lite up a pair of 450TL's...
7.5v @ 12amps, each.
